This powerpoint presentation begins by providing a brief overview of the Cedar Rapids
Water Department goals and the water system. The issue of ammonia in the source water and virus disinfection is presented, along with the long chloramine contact time required for
virus CT, the benefits of ultraviolet (UV) disinfection, UV design criteria and procurement process, equipment and operating characteristics, UV dose requirements, project costs, and cost estimates for smaller
groundwater systems. Presentation conclusions indicate that:
UV can be an economical option for virus
inactivation despite higher UV doses;
UV provides superior disinfection capability
versus chlorine with no disinfection byproduct (DBP) issues;
UV system can be designed to easily meet
more stringent future regulations;
UV can be an economical option for virus
inactivation despite higher UV doses;
UV provides superior disinfection capability
versus chlorine with no DBP issues; and,
UV system can be designed. Includes tables, figures.
